A growing collection of Java-based examples that show how to connect to various Qlik Sense services. I decided to create these because there weren't that many examples available on the web, and the ones that were, used outdated code and ignored resource management and secure programming practices. My goal is to provide a bit more modern code that can be adapted more easily to custom solutions while providing a better starting point for all skill levels. However, software architectural concepts and SOLID principles have been mostly ignored to keep things simple. I will provide more examples as my time permits and prioritize those that are specifically requested.
- Ticket API - Shows how to request a Ticket from the Qlik Proxy Service (QPS) using standard certificates exported from Qlik Sense without needing to convert them to Java KeyStore (*.jks) certificates. Since this example uses REST, it can be easily adapted for other REST-based services, for example, calling the Qlik Repository Service (QRS).
- Engine API - Shows how to create a WebSocket client that uses standard certificates to communicate with the Qlik Engine using JSON-RPC.
- Java JDK/JRE 12+ is required, but can be adapted for Java 9+.
- IDEs that support Maven projects. Apache NetBeans 11+ is recommend due to its native support.
